CLOCK.

Application filed April 23, 1924. Serial No. 708,369.

To aZZ whom it may concern:

Be it known that 1, CHARLES H. HYDE, a citizen of the United States. residing at lVinsted, county of Litchfield, State of Connecticut, have invented a certain new and useful Improvement in Clocks, of which the following is a full, clear, and exact description.

It is frequently diflicult to determine when a clock sets level, and in case of the usual pendulum clock, it is important that it shall set level or substantially so, as otherwise it will not keep good time or run properly.

The principal object of the present invention is to provide a novel and improved device, which is capable of being embodied in a clock, for determining when the clock sets level and for assisting in thus posltioning the clock. Another object of the 1 nvention is to provide an indicatlng device of this character which is simple in construction and reliable, and which although visible from the outside of the clock to which it is applied, will not detract from the appearance thereof.

The following is a description of my invention, reference being had to the accompanying drawing, in which,

Figure 1 is a face view of a clockto whlch my improved device is shown applied;

Fig. 2 is a detail sectlonal view, partly in elevation and on an enlarged scale, taken on the line 2 2 of F 1; and

Fig. 3 is a back view of the clock dial with my improved device shown mounted thereon, the hand carrying arbors of the clock being shown in section.

The clock illustrated in the drawings '13 provided with a case 2, adial 4t which is covered by a glass door 6, hand carrying arbors 8 extending through a central aperture in the dial, and a regulating member 9 that extends through an eyelet 12 which is rivited in an aperture in the dial directly above the hand carrying arbor. As shown, my improved indicating device comprises a member 10 which is mounted or suspended at its upper end on a rivet 1r secured to a supporting plate 16 which in turn is secured to the back of the dial by the eyelet or rivet 12. The suspended member 10 is provided with a transversely extending slot 18 through which the hand arbors 8 extend, and its lower end, which is arranged near the lower end of the dial, has a projection which is shaped to form a pointer 20. This pointer 20 is bent at right angles to provide a horizontal portion 22 that extends through an elongated slot 2r concentric with the axis of the pivot of the member 10, and its extreme outer end is bent downwardly so as to enable it to move over the face of the dial. A weight or plumb-bob 26 is arranged adjacent the lower end of the member 10, and is secured to the member by means of a wire 28. the lower end of which carries the weight 26, and the upper end of which is soldered or otherwise secured to the member 10. The wire 28 is bowed intermediate its ends at 30, so as to enable the wire to be bent to vary the position of the weight 26. The member 10 is loosely mounted on the rivet 12 so as to enable it to swing limited distances with relation to the clock case, either in a direction about the axis of its pivot or longitudinally thereof.

With my improved device, as above described, it may be readily determined when the clock sets level or is tipped either side wise, or back or forward. When the clock sets level both transversely and longitudinally, the pointer 20 assumes a central position with relation to the slot 24 and is spaced a slight distance from the face of the clock dial; when the clock is tipped sidewise the pointer assumes a position at one side of the longitudinal center of the slot; and when the clock is tipped back or forward the position of the pointer with relation to the face of the dial is varied accordingly. When the pointer 20 is in front of the central portion of the slot and midway between the limits of its throw toward and from the dial, the clock base is in proper position, and the clock if properly constructed and adjusted bvi'he manufacturer will operate as desired.

As will be evident to those skilled in the art, my invention permits of various modification without departing from the spirit thereof or the scope of the appended claims.

hat I claim is:

1. A clock having, in combination, a clock case, a dail, and a device arranged back of the dial having indicating means extending through a slot in the front of the case for indicating the plane in which the base of the clock rests.

2. A clock having, in combination, a clock case, a dial, and a device for indicating the plane in which the clock rests comprising a member arranged back of the dial loosely suspended at its upper end, having its lower end weighted and having a pointer on its lower end extending through a slot in the dial so as to permit swinging movement of said member with relation to the clock case.

3. A clock having, in combination, a clock case, a dial, a hand carrying arbor extending through the dial, and a device for indicating the plane in which the clock rests comprising a member loosely suspended at its upper end on the back of the dial above said arbor, having an indicating finger on its lower end, extending through a slot in the lower end of said dial, and an adjustable weight carried by said member and located adjacent to its lower end.

i. A clock having, in combination, a clock case, a dial, a hand carrying arbor extending through the dial, and a device for indieating the plane in which the clock rests comprising a hanging member Weighted at its lower end and loosely suspended at its upper end at the back of the dial above said arbor, having an indicating finger on its lower end extending through a slot in the lower portion of said dial, said member, when the clock is set level, having its upper and lower ends in substantially the same vertical plane as the axis of said arbor.

5. clock having, in combination, a clock case, a dial, and a device arranged back of the dial and having an indicating member movable over a slot in the front of the clock case for indicating the plane in which the base of the clock rests, the plane being cLeter;/---\ mined by the angular positionavhiohthe indicating member assumes with relation to the wall of said slot.
